Abstract
The invention concerns a device with an elongated optical guide (1) and pumping means, for producing by stimulated emission an optical signal (4) under the effect of an optical pumping by a pump wave (6), the stimulated emission from the active elements of the guide having been excited by the pump wave. The invention is characterized in that the single-crystal guide having a core (3) doped with active elements and a non-doped peripheral cladding (2) enables the pump wave to be guided and confined in its entire volume, the optical signal (4) produced in the core being freely propagated (8),the optical indices of the core and the cladding being sufficiently close to avoid guiding in the doped core. In an implementation mode, the guide has a shorter length than the length of an optical signal Raleygh length in the guide. The device can be implemented in impulse optical amplifiers or laser oscillators.
